MACHINE FOR DRILLING TIRES AND FELLIES OF WHEELS.

SPECIFICATION forming part of Letters Patent No. 576,305, dated February2, 1897.

Application filed January 28, 1896. Serial No. 577,109. (No model.)

To all whom it may concern.

Be it known that we, ELBRIDGE S. FELTGH and CHARLES E. STONE, citizensof the United States and residents of Ainesbury, in the county of Essexand State of Massachusetts, have invented certain new and usefulImprovements in Machines for Drilling the Tires and Follies of Wheels,of which the following is a specification, reference being had to theaccompanying drawings, forming a part thereof, in which similar lettersof reference indicate corresponding parts.

This invention relates to drilling-inachines, and particularly to thatclass thereof which are designed for use in boring the tires and felliesof wheels and countersinking the bores in the tire; and the objectthereof is to provide a machine of this class which is so constructedand arranged that the wheel after having been placed upon the machine isretained thereon until the entire operation is completed, said Wheelbeing revolubl y supported and being turned on its support until theentire tire and the fellies are suitably bored; and with this and otherobjects in View the invention consists in the construction, combination,and arrangement of parts hereinafter described and claimed.

It is necessary to employ different drills in boring the tires, thefollies, and countersinking the bores in the tires of wheels, and atleast three different drills are required, and in most machines of thisclass it is necessary to take the wheel from the machine while changingthe drills, but in our improvement this difficulty is avoided, and weemploy a revoluble tripod, which may be provided with any desired numberof drill-heads, and these different drill-heads are adapted to carry thedifferent drills required.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawings form a part, in which Figure 1 is a sideelevation of our improved drilling-machine; Fig. 2, a plan view thereof;Fig. 3, a side elevation of one form of tripod which we employ, showingone drill-head connected therewith; Fig. 4:, an end view thereof,showing three drill-heads Fig. 5, a section on the line 5 5, lookinginthe direction of the arrow a; Fig. 6, an end view of a plate providedwith a central tubular extension by means of which the tripod and thetripodspindle are connected with the frame of the machine. Fig. 7 is aplan view of a modified form of turret, showing two drill-headsconnected therewith; Fig. 8, a section on theline 8 8 of Fig. 7, andFig. 9 is a side elevation of a sleeve which forms a detail of theconstruction shown in Fig. 7.

In the practice of our invention we employ a frame comprising endstandards A and A which are united at the top by horizontal side bars Aand A, and thohorizontal side bars A and A" are firmly connected bycross-bars or plates a, a and (t and this frame is composed, preferably,of wood, and is also made strong and substantial, but the exact formthereof is immaterial, as is also the method of its construction.

.Pvassin g centrally and longitudinally through the lower portion of theframe is a shaft 13, which is provided with three pulleywheels B B and13*, which are of different sizes and increase insize in the ordernamed, and on the outer end of said shaft is a powerwheel B to which inpractice apower-belt is applied.

Secured to the cross pieces or bars a and a in the top of the frame, andon the upper sides thereof, are housings C and 0 through. which thedriving shaft or spindle D passes, and mounted on said driving shaft orspindle D are pulley-wheels D ,D ,and D which decrease in size in theorder named, and said pulleywhcels are designed to be operated bybelts Eand E, which are mounted on the wheels D and D* and also on the wheels13 and B on the shaft B, and it will be understood that either one ofthese belts may serve to operate the driving shaft or spindle D, andthat two orthree thereof may be employed, if required.

The driving shaft or spindle D is movably mounted in the housings O andO and is adapted to be moved longitudinally therein, and in thisoperation it passes through said housings in the usual manner, and thepulleywheels D D and D are also connected therewith as usual in thisclass of devices, and these elements of construction are allsubstantially the same as those heretofore employed in this class ofmachines and form no part of our present invention. In order to operatethis shaft, we connect with the outer end thereof a lever F, and thislever is connected with the shaft by a collar F in the usual manner,said collar being held in place by rings or bands F one of which ismounted at each side thereof, and said lever is connected at one endwith the frame, as shown at F and the handle thereof extends across thebar F which is also connected with the frame and on which the handle endof said lever is free to slide.

The inner end of the driving shaft or spindle D is provided with a headd, in the outer end of which is formed a central cavity or recess d(shown in dotted lines in Figs. 3 and 7,) and which is adapted toreceive the end of a drillspindle, and at each side thereof is formed acavity or recess (1?, also shown in dotted lines in said figures, whichare adapted to receive pins or projections secured to the drill-spindle,which is mounted in the drill-heads, as hereinafter described.

\Ve also employ a turret, which consists of a head G, which is shown inFigs. 3, 4, and 5, and which, as shown in the drawings, is provided witha number of drill-heads G but one of which is shown in Fig. 3 and threeof which are shown in Fig. 4, and this turret is adapted to be connectedwith a turret-spindle g by means of a rivet g as shown in Fig. 3, andsaid turret-spin dle is passed through a sleeve which is formed on aplate 9, which is bolted to the cross-bar a of the frame, as shown inFig. 1, and the end of the turretspindle 9 extends through saidcross-bar a of the frame and is provided with a circular head, ring, orband g, between which and the plate g or cross-bar a is mounted a strongspiral spring g, and secured in the outer end of the sleeve g" is a pin(shown in dotted lines in Fig. 3,) which is adapted to project into acavity or recess formed in. the adjacent end of the head G, and alsoshown in dotted lines in said figure.

Each of the drill-heads G consists of a band H, through which passes adrill-spindle 72, (shown in dotted lines in Figs. 3 and 7,) the outerend of which is provided with a head 7L2, which is provided centrallywith a hole or opening 72 into which the drill or tool is adapted to beinserted and wherein it may be fastened by means of a set-screw h, andthe inner end of the spindle 7t is provided with a collar or band h,which is secured thereto in any desired manner and which is providedwith pins or projections h, which are adapted to enter the holes oropenings d in the head (Z of the driving shaft or spindle D, and formedon the end of the drill h is a conical projection 7L7, which is adaptedto enter the conical cavity or recess (1 which is also formed in thehead (Z of the drive shaft or spindle D. It will be understood that bymeans of this construction the drill-spindle h is free to revolve in thetubular head or sleeve II and that any number of these tubular heads orsleeves may be employed, three thereof being shown in Fig. 4, and inFig. 2 we have shown an ordinary drilling-tool H connected with one ofthese drill-spindles and a reamingtool H connected with another.

Ve also provide a wheel-cup K, which is mounted at the forward end ofthe frame of the machine and is capable of vertical ad justment by meansof a screw or screws K (shown in Fig. 1,) and this wheel-cup is alsocapable of longitudinal adjustment on the supports thereof, which areshown in dotted lines at K in saidfigure, and secured to the upperportion of the frame of the machine and to the side bars A and A thereofare verticallyadjustable spring-supports 71:,which are adapted tosupport the tire of a wheel and which are vertically adjustable by meansof screws k one of which is shown in Fig. 1, and secured longitudinallyand centrally of the frame between said supports is a sliding plate L,the end of which is provided with a metal block L which is connectedtherewith by means of a tongue-and-groove or dovetailed coupling, asshown at L and the outer sur face of this block is slightly curved orsegmental in form, so as to correspond with the form of a felly of awheel, and these blocks L are preferably just the length of thefellyplates between the holes, and by placing the joint of the felly atone end of a block and drilling one hole and then placing the joint atthe other end of the block and drilling the other hole these holes willcome exactly right for the felly-plates and without marking the same.

Secured to the side bar A of the frame and to the upper surface thereofis a plate-spring M, which is adapted to project over the tire and fellyof a wheel' when the the latter is in position, as shown in Fig. 2, andpivotally connected with said spring is a rod m, the lower end of whichis connected with a footpedal m as shown in Fig. 1, and the operation ofthis form of construction will be readily understood from the foregoingdescription, when taken in connection with the accompan yin g drawingsand the following statement thereof.

It will be understood that the turret-spindle g is adapted to slide inthe plate g and the sleeve 9 which is formed thereon, and theturret-head G is rigidly connected with the outer end of theturret-spindle, and in order to drill the holes for the tire-bolts thehub of the wheel is placed in the wheel-cup, as shown in Fig. 2, and thetire and felly on the hearings or supports 70, and the spring M is thenforced down by means of the pedal m onto the tire, and by this operationthe wheel is firmly held in position. In order to drill a tire, theturret-head G is turned until the drill-head II, provided with therequired drill or tool, is opposite the driving-spindle D. The saiddriving-spindle is then brought forward by means of the lever F, inwhich operation it connects with the drill-spindle h, as hereinbeforedescribed, and in order to ICS countersink thc drill-holes in the tireto provide room for the heads of the bolts the drivespindle is movedbackward and the turrethead turned so as to bring the drill head orspindle provided with the reaming-drill into line with saiddriving-spindle, and the operation above described is repeated, andafter the bore in the tire has been countersunk the turret-head is againturned so as to bring the spindle provided with the drill which isdesigned for use in boring fellies into line with the driving-spindle.

It will thus be seen that the tire may be bored and the bores thereofcountersunk and the fellies bored without moving the wheel from themachine, all that is necessary being to revolve the turret-head so as tobring the drill-spindle provided with the necessary tools into line withthe driving-spindle D, and all that is necessary in order to bore thetire and the fellies and to countersink the bores of the tire, as abovedescribed, throughout the entire circumference of the wheel is to simplyrevolve the wheel in the wheel-cup and to operate the turret-head andthe driving-spindle as above described, and this operation can beperformed as rapidly and expeditiously as desired. lVhen the lever F isoperated in this manner, the driving spindle slides through the pulleysD D and D and the housings O and (l and the clutching device on the endof the driving-spindle, which consists of the head 61, provided with theholes or openings d and d engage with the corre sponding devices on theend of the drill-spindle h, as hereinafter described, and saiddrillspindle turns easily with the sleeve or head If. The differentsizes of drills are held in the drill-spindle h by the set-screw h andthe turret-head is drawn back each time that the driving-spindle D ismoved backward by the spring 9 thereby drawing the drills out of thewheel or the tire and fellies thereof, and in the process of drilling,as hereinbefore described, the driving-spindle D forces the turret-headG away from the plate 9 and the sleeve 9 connected therewith, by drawingthe turretspindle g therethrough and by compressing the spring g betweenthe cross bar a and the plate 9 After releasing the lever F the spring 9draws the turret-head G back to its place, or to the position shown inFig. 3, and the driving-spindle goes back far enough to allow theturret-head to be revolved in such manner that the drill-heads H willnot strike the end of the driving spindle.

The turret-head G is held in each respective position by means of thepin or pins g", connected with the end of the sleeve 9 and operating inconnection with the corresponding hole or holes g ,for1ned in theturret-head, and in order to avoid confusion we have only shown one ofthe drill-heads in Fig. 3 but it will be understood that any desirednumber thereof may be employed,and the inner end of the turret-spindle 9projects within the rim of the pulley d which is mounted on thedriving-spindle so as to employ as little space as possible, and bymeans of the vertical and longitudinal adjustment of the wheel-cup weprovide for drilling wheels of different diame' ters and provided withtires and fellies of different widths or thicknesses.

In Figs. 7, 8, and 9 we have shown a modification of the turret-headshown in Fig. 3, and hereinbefore described, and this form ofconstruction may be adapted instead of that shown in Fig. 3, ifpreferred. In this construction each of the drill-heads is capable oflongitudinal movement independent of the other and slides on or in thehead G. In this form of construction we provide a tubular head G, whichis provided with a central bore drilled to within about one-half inch ofthe outer end thereof, and the outer surface of the tubular head G isprovided with a plurality of dovetailed grooves N, four of which areshown in Fig. 8, and the drill heads or sleeves H are provided withshanks n, to which are secured or on which are formed arms M, which areadapted to slide in said dovetailed grooves, and passing through theinner end of each of said arms is a set-screw O,the inner end of whichpasses through a slot 0 formed in the bottom of the dovetailed grooves,and the inner end of the set-screw O is reduced in size and adapted toenter an annular groove 0 formed in the spindle g. The spindle 9 may beconnected with the frame of the machine in any desired manner, and thatportion of the end thereof within the turrethead G is reduced in size,and mounted thereon is a spiral spring 9 and mounted on the inner end ofthe reduced portion of the spindle g is a tubular sleeve P, the outerend of which is provided with a flange F on which is formed one or moreprojections or shoulders P.

It will be understood that any desired number of the drill-heads H maybe employed, and that each turret-head G maybe provided with any desirednumber of the dovetailed grooves N, and that a corresponding number ofthe drill-heads H maybe employed, and that each of said drill-heads isprovided with an arm n and a set-screw O, and that each of thedovetailed grooves N is provided with a slot 0 which communicates withthe central bore of the turret-head, and the shoulders or projections Pare adapted to operate in. connection with the inner ends of theset-screw O, which project through the space between the turret-head andthe reduced end of the spindle g and into the annular groove 0 formedtherein. Said spindle g is also provided at-one side thereof with alongitudinal groove or recess R, in which the inner end of the setscrew0 is adapted to slide; and in the operation of this form of constructionwhen the drive-spindle D is operated and brought in contact with one ofthe drill-heads the arm a connected therewith, is forced outwardly, andin this operation the inner end of the set-screw 0, connected therewith,slides in the groove R in the spindle g, and said setscrew compressesthe spring 9 by forcing outwardly the sleeve P, and each of the otherdrill-heads is held stationary by the inner end of the set-screw 0,connected therewith, which remains in the annular groove 0 and wheneverthe drive spindle or shaft D is moved backwardly the spring 9 will atonce return the drill-head, which has been forced outwardly, to itsnormal position, in which position the inner end of the set screwO,connected therewith, will project through the annular groove 0 in thespindle g, and the tripod-head may be again revolved, so as to bringanother drill-head in line with the driving-spindle. It will thus beseen that this form of construction is substantially the same in theresults produced as that hereinbefore described, the principaldifference being that in this form each of the drill-heads movesindependently of the other or slides independently thereof.

It is evident that other changes in and modifications of theconstruction herein described may be made without departing from thespirit of our invention or sacrificing its advantages; and we reservethe right to make all such changes in and modifications of theconstruction as fairly come within the scope of the invention; andthough we have described our improvement as a machine for drilling wheel-tires, &c., it is evident that the same may be employed for drillingmany other articles and as a drilling-machine for general purposes.

Ve also employ an idler by means of which two different speeds maybeobtained without stopping the machine, and this device is operated soas to loosen one of the belts E or E and tighten the other, and it isconnected with the side of the frame and consists of the parts S, S Sand S, which are connected by means of set-screws, but these devicesform no part of this invention and the construction and operationthereof are not therefore described in detail.

Having fully described our invention, we claim as new and desire tosecure by Letters Patent 1. In a machine for drilling the tires andfellies of a wheel, the combination of a drivin g spindle or shaft, arevoluble turret mounted in front thereof, and provided with drillheadswhich are adapted to be brought in line therewith, said machine beingalso provided with a wheel-cup which is adapted to receive the hub of awheel and to support the wheel in horizonal position in such manner,that the tire thereof, will be in line with the driving or drill shaft,and said frame being also provided with an adjustable plate providedwith a block or head which is adapted to press upon the inner side ofthe felly of the wheel, and said frame being also provided at each sideof said adjustable plate with vertically-adjustable supports for thetire of the wheel, and with a plate-spring which is adapted to pressupon the upper side of the tire, and a rod pivotally connected therewithand with a foot-pedal, substantially as shown and described.

2. In a tire-drilling machine, the combina tion ofalongitudinally-movable driving spindle or shaft, and means foroperating the same, of a plurality of drilling-heads each of which isconnected with a central head which is revolubly mounted on a spindle,and each of which is provided with a drilling-spindle, with which adrill or other tool may be connected, and each of said drilling-headsbeing also adapted to be brought in line with the driving spindle orshaft, and said central head with which the drilling-heads areconnected, being also longitudinally movable, and the spindle by whichit is supported being passed through a plate provided with a sleeve ortubular extension, and which is connected with the frame of the machine,substantially as shown and described.

In testimony that we claim the foregoing as our invention we have signedour names, in presence of the subscribing witnesses, this 18th day ofJanuary, 1896.
